Answer: Obtuse
Step-by-step explanation:
The converse of the pythagorean theorem has 3 cases
- If
then the triangle is acute. - If
then we have a right triangle. - If
then the triangle is obtuse.
a = 2, b = 2, c = 3 are the three sides. C is always the largest side.


We can see that
(since 8 < 9), which leads to the triangle being obtuse. The obtuse angle is opposite the longest side.
You can use a tool like GeoGebra to confirm the answer.
